This is a 128k x 8 bit high performance static cmos storage
The IDT71024 CMOS static RAM provides 128K × 8‑bit (1 Meg) memory organized in a high‑speed static architecture. It is available in 300‑mil and 400‑mil Plastic SOJ packages and operates over commercial (0 °C to +70 °C) and industrial (‑40 °C to +85 °C) temperature ranges.
Key electrical characteristics include a 5.0 V supply (±10%), input and output leakage currents of ≤5 pA, and power dissipation of 1.25 W. Access times range from 12 ns to 20 ns depending on speed grade, with read and write cycle times matching these specifications. The datasheet also details pin configurations, timing waveforms for read/write cycles, ordering information, and document revision history.
